Minimum Equipment List (MEL)

A Minimum Equipment List (MEL) is a document that outlines the essential equipment and systems an aircraft must have operational to fly safely within specific conditions. It allows operators to perform flights with certain non-critical items temporarily inoperative, provided they won't affect safety or compliance. The MEL is approved by aviation authorities and tailored to each aircraft type. It helps balance safety with operational efficiency, ensuring that minor equipment issues don’t unnecessarily delay or cancel flights, as long as safety standards remain met.
